To all whom it may concern Be it` known that we,Y JOHN-R, Kann and @Hernals L. SiinrPAiin, citizens ofthe UnitedStates, residing. at Tracy, inv the county of San Joaquin, State of'California,

have invented certain new and useful Ini-k provements in HydrocarbonBurners; and we dodeclare the. following to be a full, clear, y

and exact descriptionjof the same, refer ence being had to the accompanying ldr awings, a r.df to the charactersv ofreference marked thereon, which'form a part ofthis application.

Thisinvention, relates to improven'ients in hydrocarbon burners of a typeadapted to be placed in ordinary'doinestic wood 'or coal burning ranges or stoves and particularly designed to use kerosene or gasoline and convert the same into gas before burning the same.

The principal object ofthe invention is t0 produce a burner of thistype in which.,l simplicity of construction and efficiency of Operation are combined inthe highest degree, which is so constructed that the tendency to leak at a vital point is reduced to a minimum. Y. l

LWe have found from experience that if ai somewhere inthe vicinity-of the raw fuel in- Y take,V while Vnot desirable. is apparently harmless as far as being aid t0 the formation of carbon is concerned. l

With this in mind we have so construct ed our burner that the same will have no connections of any kind above the line of lire, thereby insuring efficiency fof operation and longevity of the burner.

Further, the burner is so made that the gas passages will be perfectly smooth, thereby avoiding any tendency to form carbon deposits owing to any roughnesses or protuberences in the passages.

These objects we accomplish by means' of such structure and relative arrangement of parts as will fully appear by a perusalof the following specic'ation and claims.

' n the drawings similar characters of reference indicate corresponding partsin the several views.

Fig. 1 is an elevational view ofthe burner showing the samepositioned in thefireb'ox' 0fv a range. i

Fig. 2-is a vertical `sectionof the burner. Referring now more particularly. to the characters of reference on the drawings, the

numeralV 1,., denotes aI substantially solidI metal" cylinder or base which servesjasafire plate and which has a horizontal 'rim or:flange 2 adjacent its upper face overhanging the sides 0f the cylinder. 1 l Y Y The underside ofthe kbase is providedY with:l a ktapped hole 3 to ieceivethe threaded encl-V 4 ofa supply pipe 5,'which sulpports the burner -and preferably restsy on the fireboX grate 6 of a range 7, the pipe having a. needle valve 8 interposed therein', outside the. range, tof controlfthe supply oufy fuel through the pipe.

Artransverse hole9 isdrilled through the base4 libelow the rim 2 tocominiinicate with .the holeff', its outer ends being tapped rightVV `an'dleft hand respectively.:y

Extendingajbove the base and in a verti- Vcal and diametrical plane i'f herewith is an 4arched-.pipe 1-OA havinga very small4 hole 11 on its .under isidedirectly'above the center ofthe Iplate, .This pipe"- passesl belowthe levelf ofthe rim 2- of tlie'base 1, the ends thereof; then being bent toward eachother f onv a horizontal plane. @ne 'of such ends 1,2. is threaded with a right hand dieandl the otliei'end` 18 has laleft hand thread", to enable such ends to fit into the correspondingly tapped hole 9. i Y

This of course is easily accomplished by inserting the member 1 Vbetween the ends of the pipe by springing thesame apart", and then turning either member relative tothe other in the proper direction.

We preferably emp-loyan ordinary vpiece of'iron pipe suitably bent to shape rather' than a casting,V both for cheapness of manufacture and ease of assembly and because it is almost impossible to obtain a hollow casting of such small dimensions in which the inner face 0f the walls will be perfectly smooth and the walls themselves -of equal thickness throughout.

In operation, the base some suitable means and the vfuel-admitted through the pipe 5. As soon as it reaches the c c 105 1 is first warmed by A Y ignited.

The flames will of course rise with vthe natural draft in the stove and will never pass below the top of the plate i. In fact,

' even after the burner has been voperating for some time, the hand may be placed thereon in the vicinity of the pipe 5 without danger of burning the same.

The overhanging rim or flange 2 also serves to protect the screw connections of the pipe 10 with the base from any possible heat and thus insuring that the threads will not be subjected to undue expansion and contraction which would tend to cause leaks.

From the foregoing description it will be readily seen that we have produced such a device assubstantially fulfills the vobiect of the invention as set forth herein.

'.W'hile this specification sets forth in detail the present and preferred construction of the device still in practice such devia- Vtions from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claims.

Having thus described our invention what we claim as-new and useful and desire to secure by Letters Patent is l. A hydrocarbon burner comprising a metal member serving as a. burner plate, an oil supply pipe connected thereto, and a separate hollow arch-shaped member extending above said plate and spanning the same and provided Vwith an. orifice to discharge fuel onto the plate, the arch having threaded connection at both ends with the plate below the line of the ire'thereon and communicating with the supply pipe in said plate.

2. :A hydrocarbon burner comprising a base serving as a burner plate, the same being provided with a tapped hole to receive an oil supply pipe and with a transversely drilled hole communicating therewith, the

outer ends of the latter hole being tapped riglzit and left hand respectively and being on a horizontal plane considerably below the top of the plate, and a hollow arched pipe provided with an orifice adapted to discharge fuel gas onto the plate spanning the same and projecting thereabove, the lower ends of said arch being bent toward each other and threaded right and left hand respectively, whereby they may be secured in the tapped holes of the base.

3. A .hydrocarbon burner comprising a metal member serving as a burner plate, an oil supply pipe connected thereto, and a separate hollow, continuous and smooth inner surfaced arch spanning the plate and provided with an orifice adapted to discharge fuel gas thereon and extending thereabove and connected thereto below the line of the iire on said plate, and having communication with the supply pipe therethrough.

4. A hydrocarbon burner comprisingv a metal member serving as a burner plate, an oil supply pipe connected thereto, a hollow arch-shaped member extending above the plate and provided with an orifice adapted to discharge fuel gas thereonto, said arch having threaded connectionwith the sides of the plate below the top thereof and communicating with the supply pipe through the plate, and a rim on the plate overhanging the sides thereof above the threaded connections and shielding the latter. y

A burner comprising a hollow base having an inlet; and a one-piece arch provided with a combustion orifice, the ends ofthe arch having oppositely'thrcaded connection with opposite sides of the base, the arch being suciently resilient to permit thebase to be introduced between the ends'of the arch, the arch and the base being relatively Vmovable to secure threaded connection between thc ends of the arch and the base.

in testimony whereof we affix our signatures.
